Gebiet der ErfindungTerritory of invention
Eine
derartige Radlagereinheit ist in
Üblicherweise weisen Radlager wenigstens eine aber zumeist zwei oder mehr Innenlaufbahnen für Kegelrollen direkt an einem Radträger oder an einem bzw. mehr Außenringen auf. Der oder die Außenringe sind in einem Radträger aufgenommen. Der Radträger ist mit einem oder mehreren Flanschen versehen. In der Regel dient ein Flansch zur fahrzeugseitigen Befestigung des Radträgers oder zur Befestigung eines oder mehrerer Fahrzeugräder an dem Radträger. Im zuletzt genannten Fall ist die Nabe fahrzeugseitig befestigt und die Innenlaufbahnen rotieren um die feststehende Nabe. Wenn der Radträger fahrzeugseitig fest ist, ist die Nabe drehbar mittels des Radlagers drehbar in dem Radträger gelagert, wodurch die Außenlaufbahnen gegenüber den fahrzeugfesten Innenlaufbahnen drehbar gelagert sind. An der Nabe ist/sind in diesem Fall ein oder mehrere Fahrzeugräder befestigt.Usually wheel bearings have at least one but mostly two or more inner raceways for tapered rollers directly on a wheel carrier or on one or more outer rings on. The outer ring (s) are in a wheel carrier added. The wheel carrier is provided with one or more flanges. Usually serves a flange for securing the wheel carrier on the vehicle or Attachment of one or more vehicle wheels to the wheel carrier. in the the latter case, the hub is attached to the vehicle and The inner raceways rotate around the fixed hub. If the wheel carrier on the vehicle side is fixed, the hub is rotatable by means of the wheel bearing in the wheel carrier stored, causing the outer raceways compared to the vehicle-fixed inner raceways are rotatably mounted. At the hub is / are in this case one or more vehicle wheels attached.
Es ist bekannt, dass Schrägrollen- insbesondere Kegelrollenlager auf Grund des durch die Konstruktion vorgegebenen Kontaktwinkels in der Lage sind sowohl radial zur Rotationsachse wirkende als auch axiale, also mit der Rotationsachse des Radlagers gleichgerichtet wirkende Kräfte bzw. Komponenten von Kräften über die Laufbahnen aufzunehmen. Zusätzlich müssen für die Flanken der Rollen jedoch Axialstützen vorgesehen werden, die das axiale Auswandern der Rollen aus den Laufbahnen verhindern. Diese Axialstützen sind üblicherweise über die Laufbahnen der Innenringe des Radlagers hinaus stehende Borde an den Innenringen an denen die Stirnflächen der Kegelrollen anlaufen.It it is known that tapered roller especially tapered roller bearings due to the construction predetermined contact angle are both radial to the axis of rotation acting as well as axial, so with the axis of rotation of the wheel bearing rectified forces or components of forces over the To record raceways. additionally have to for the Flanks of the rollers, however, axial supports are provided, the prevent the axial migration of the rollers from the raceways. These axial supports are usually about the Runways of the inner rings of the wheel bearing outboard rims the inner rings on which start the faces of the tapered rollers.

ZusammenfassungSummary
Die Aufgabe der Erfindung ist es daher, eine Radlagereinheit zu schaffen, die robust ist, deren Innen- und Außenlaufbahnen sich kostengünstig herstellen lassen und deren Einzelteile sich einfach montieren lassen.The The object of the invention is therefore to provide a wheel bearing unit, the robust, whose inner and outer races are inexpensive to produce and their items can be easily assembled.
Diese Aufgabe ist dadurch gelöst, dass die jeweilige einer Innenlaufbahn zugeordnete Axialstütze ein einteilig mit der Innenlaufbahn ausgebildeter Bord ist. Wenn die Innenlaufbahnen) direkt an dem Radträger angeordnet sind, ist der oder sind die Borde demnach einteilig und einmaterialig mit dem Radträger ausgebildet. Die Innenlaufbahnen) ist/sind vorzugsweise an einem Außenring ausgebildet, der in den Radträger montiert wird. In diesem Fall ist jeder der Innenlaufbahnen jeweils ein Bord zugeordnet, wobei die Innenlaufbahnen vorzugsweise axial zwischen den Borden verlaufen, d.h. die großen Stirnflächen der einen Reihe Kegelrollen sind von den großen Stirnflächen der axial benachbart liegenden Reihe Kegelrollen abgewandt.These Task is solved by that the respective axial support assigned to an inner raceway is integrally formed with the inner race board. If the Inner raceways) are arranged directly on the wheel carrier, is the or are the shelves therefore one-piece and einmaterialig with the wheel carrier educated. The inner raceways) is / are preferably at one outer ring trained in the wheel carrier is mounted. In this case, each of the inner raceways is respectively associated with a shelf, wherein the inner raceways are preferably axially between the shelves, i. the big faces of a number of tapered rollers are from the big ones faces facing away from the axially adjacent row tapered rollers.
Die Innenringe sind ohne Bord und somit einfacher zu bearbeiten. Die Baueinheit ist einfach zu montieren. Die Anzahl der Einzelteile und somit der Montageaufwand ist reduziert.The Inner rings are without a board and thus easier to work. The Assembly is easy to assemble. The number of items and thus the assembly effort is reduced.
Eine Ausgestaltung der Erfindung sieht das Radlager als eine Baueinheit vor, die komplett einem oder zwei Innenringen sowie mit oder ohne Nabe vormontiert in einen Radträger montierbar ist. Dazu weist das Radlager pro Innenring wenigstens eine Axialsicherung auf, die mit dem jeweiligen Innenring in einer Wirkverbindung steht. Die Axialsicherung schließt sich dazu seitens des kleinsten Durchmessers der Kegelrollen axial an die Kegelrollen an und steht mit dem Innenring in einem formschlüssigen Eingriff. Die Axialsicherung steht radial über den kleinsten Durchmesser der jeweiligen Außenlaufbahn an dem Innenring hinaus und steht so den Stirnflächen der Kegelrolle seitens des kleinsten Durchmessers der Kegelrollen axial gegenüber. Das Radlager kann vormontiert transportiert und gehandhabt werden, da die Axialsicherung durch den Kontakt mit den kleinen Stirnflächen der Kegelrollen die Kegelrollen und den Außen- und Innenring aneinander hält. Die Axialsicherung hält alternativ dazu die Einheit durch den axialen Kontakt mit einem Käfig anstelle des direkten Kontaktes mit den Stirnseiten, in dem die Kegelrollen geführt sind, aneinander. Die einfachste Form der Axialsicherung ist in diesem Fall ein Sicherungsring, der in eine Ringnut an dem Innenring eingreift.An embodiment of the invention provides the wheel bearing as a structural unit which is completely assembled in one wheel carrier, one or two inner rings and pre-assembled with or without hub. For this purpose, the wheel bearing per inner ring on at least one axial securing, which is in operative connection with the respective inner ring. The axial lock adjoins axially by the smallest diameter of the tapered rollers to the tapered rollers and is in a positive engagement with the inner ring. The axial securing is radially beyond the smallest diameter of the respective outer race on the inner ring and is thus axially opposite the end faces of the tapered roller on the part of the smallest diameter of the tapered rollers. The wheel bearing can be transported and handled pre-assembled Since the axial securing by contact with the small faces of the tapered rollers keeps the tapered rollers and the outer and inner ring together. Alternatively, the axial lock holds the unit together by axial contact with a cage instead of direct contact with the end faces in which the tapered rollers are guided. The simplest form of axial securing in this case is a securing ring, which engages in an annular groove on the inner ring.
Eine weitere Ausgestaltung der Erfindung sieht vor, dass die Axialsicherung direkt an einem Käfig für die Kegelrollen ausgebildet ist. In diesem Fall greift die Axialsicherung von dem Käfig aus in eine Ringnut des Innenringes formschlüssig ein. Eine derartige Axialsicherung ist beispielsweise eine oder sind vorzugsweise mehrere am Umfang des Käfigs aus Kunststoff angeordnete Schnappnassen, die beim Aufschieben des Käfigs mit den Wälzkörpern auf den Innenring auffedern und dann in eine entsprechende Ringnut am Innenring einfedern.A Further embodiment of the invention provides that the axial securing directly on a cage for the Tapered rollers is formed. In this case, the axial lock engages from the cage from a form-fitting into an annular groove of the inner ring. Such axial securing For example, one or more are preferably on the perimeter of the cage Plastic arranged snap-in, which when pushing the cage with the rolling elements on auffedern the inner ring and then into a corresponding annular groove on Press in inner ring.
